Fig. 2From: Overexpression of the Barley Nicotianamine Synthase Gene HvNAS1 Increases Iron and Zinc Concentrations in Rice GrainsNorthern blot analysis of HvNAS1 gene expression in transgenic lines. The HvNAS1 ORF was used as a probe. Total RNA was extracted from the shoots of 44-day-old plants grown hydroponically under Fe-sufficient conditions, and 20 μg of total RNA was loaded into each lane. Ethidium bromide staining was used to ensure equal loading of rRNA. NT non-transgenic line; 35S, 35S-HvNAS1 transgenic line; AN1, AN2, and AN3, OsActin1-HvNAS1 transgenic lines.Back to article page
